Object Name: M 22 (NGC 6656)
Object Type: Globular Cluster
Constellation of Sagitarius
Location: Talaveruela de la Vera-Cáceres;SPAIN
Date: 17/07/2010
Media: graphite pencil, white paper, inverted GIMP 2
Telescope: SCT 8″
Eyepiece: 31 mm Hyperion-Aspheric
Mag.: 65X

Spanish-English translation using Google Language Tools:
M22 is an impressive globular cluster in the constellation Sagittarius. It
is located at a distance of approximately 10,000 years light. The cluster is
brighter than an observer can see the northern hemisphere and only than
Omega Centauri and 47 Tucanae.
The picture at the bottom is an extension of M 22 scanned at higher
resolution.

Inside M13: A River in Darkness

Hello friends, I want to share with everyone an unforgettable experience, a journey inside the globular cluster M13.

Object Name: M13 (NGC 6205) Globular Cluster
Location: Benacebada, Granada (Spain)
Date: 2010.07.09
Media: graphite pencil, white paper.

Telescope: 16″ Dob. The observing conditions: with new moon, the seeing and transparency excellent.
For details inside of M13 I used maximum magnifications 523X (3,5 Hyperion eyepiece):It shows well defines bands of stars.The most spectacular was the dark zone or region near the center. Like a river of darkness.

I hope you enjoy it!

A Great Globular Cluster of the Southern Crown

This lovely globular cluster was first discovered by Nicolo Cacciatore
on 19th of March 1826, and later in the same year by James Dunlop.

In the 56cm dob it is quite impressive, and proved to be a challenge to
sketch as the night was cold with a stiff breeze buffeting the telescope
at intervals.

While the wind made me feel like I was rounding the Horn- I persevered,
and by 1.00am it suddenly died off allowing me to complete the finishing
touches in reasonable comfort.

Older by Globular Cluster Standards

NGC 6341, M92 Constellation Hercules, ~25,000 LY away
Globular Cluster, Class IV, 011.2’, m6.4v, 17h17.1m +43°08’
Luminosity 150,000 suns, diameter 80 light years

H: >90%, Temp: 19.3°C

Johann Bode discovered this globular cluster in 1777. Charles Messier
added it to his catalog 1781. Reading about this cluster in my NSOG vol.
2, it’s interesting to find that this cluster is only about 60%
luminosity of the globular cluster M13 found in the keystone of
Hercules. The stars lack the abundance of iron and other elements
heavier than H and He, which means that it most likely would have been
formed before those heavier elements were introduced into our Galaxy.
Even though globular clusters are the oldies of our Galaxy, the
deficiency of a rich iron and heavy elements makes M92 even older by
globular cluster standards.

M92 appeared almost elongated and irregular with a very dense bright
core and resolved abundance of stars that spread further from each other
moving outward.

Sketch created scopeside with white photocopy paper, #2 pencil and an
ultra fine black marker.

Glorious Globular

Messier M5
Observed at Bristol UK

5th June 2010; 00:30am using Nexstar 8SE

Sketched at the scope over 30 mins using a black on white template and transfered to Photoshop. I could observe several coils of stars around a bright and mottled core with sparks of light (resolved stars) across the disk and at the edges under the highest magnification.

Globular Cluster in the Eagle

A Globular Cluster in the Eagle (NGC 6760)

Sketch and Details by Ferenc Lovró

Faint, diffuse globular cluster with a perfect circular shape and a core that’s getting brighter only very gently. For me it was not resolveable, although it shows a faint star on its southern side, that may be a part of the cluster. Unfortunately the Jászszentlászló sky that was excellent this far was now ruined by the quickly increasing humidity in the air. Fortunately meanwhile this happened, the seeing got much better, so it made me a little happier on this almost Winter-like night. SQM reading: 21.20 m/arcsec^2, 9°C.

A Piece of Sagittarius

Sketch information:
Object name: A piece of Sagittarius
Scope: Skywatcher dobs 1200/200 + SWA 32mm
Place: Poland, Silesia, Skrzyszow
Seeing: 8/10 Transparency: 4/5
Date and time: 10.07.2010r, 23:50PM (21:00)
Technique: Pencil, GIMP
Author: Marek Płonka (Poland, Silesia)

Note: I’ve always used only pencil.
I use GIMP only to improvement brightness, contrast, resize and crop
images.Under clear, summer skies I was able to sketch this nice view.
I drew this picture moving from star to star, taking the view and sketching.
In my location there are still not dark nights, but I hope, you enjoy my view.

Spanish-English translation using Google Language Tools:
The globular cluster M 13 is my favorite to teach my friends. When my
friends look through the eyepiece you always hear the cry: Ohh! How
beautiful! No doubt this cluster is of the most beautiful and
impressive from the sky. It is located at a distance of 24,000 light years.
When I look at M 13 I never forget the small galaxy NGC 6027. It’s very nice to
see a galaxy and a globular cluster at a time.
